Charge- and angle-correlated inelasticities in collisions of bare fast carbon ions with neon

Abstract

We have studied the detailed energy balance in collisions of 10-MeV ${\mathrm{C}}^{6+}$ ions with Ne. In these collisions, the Ne is multiply ionized and the C ion may emerge as either ${\mathrm{C}}^{6+}$ or ${\mathrm{C}}^{5+}$. Projectile energy loss and scattering angle for a given carbon-ion charge state were determined in a high-resolution magnetic spectrograph and were measured in coincidence with the formation of a given Ne recoil-ion charge state. The amount of energy transferred to the continuum electrons exceeds, by far, the sum of the values of the ionization potentials.
